Each time a PDF file on an online web application is opened the f-secure gives me a notification 'gen:variant.kazy.39638'.
Details show me that the f-secure deletes a temporary file that is created in the 'c:\windows\Temp' for opening the pdf-file.
Belgian Defence uses clone computers. Each installation is thus the same. Only one new computer installation shows me this error.

This is your main problem:
"IE 8 and adobe acrobat 8.0"
Cloning only means that the systems are the same when installed. after the first time of use they differ, depending on what pages, URLs, PDF Flashes aso. the user surfed to.
My best advise: create a new image ASAP with IE9 and Acrobat 10 (and do not forget to include al the missing Windows updates!)
I installed all updates of the adobe 8 until 8.3.0.
I also installed the latest version of the IE explorer.
I shall now uninstall the adobe and see if it gives a difference.
But it still is a bizar problem. All other images do not show any problem.
We started to check if there is a difference in the log files and its updates (defenition files)
I would suggest you to open a support ticket for further investigation. Kindly attach a FSDIAG together with your ticket, you may include this post in your e-mail as well.
